- What does 8-32 mean on these screws?
- It is a No. 8 diameter with 32 threads per inch, a common US machine screw size. They thread into nuts, inserts or tapped holes, not into bare wood.
- What is a combination truss head?
- The head is wide and low with a drive that accepts both a Phillips and a flathead screwdriver. The wide head spreads load on thin panels and brackets.
- Can I use these outdoors?
- Zinc-plated steel is meant for indoor use. In wet or outdoor settings the plating can rust, so stainless steel is the better choice there.
- Do these come with nuts or washers?
- No. The box contains only the 100 machine screws. You need to supply matching 8-32 nuts, washers or threaded inserts separately.
- Will the truss head fit a countersunk hole?
- No. A truss head sits on top of the surface. For flush mounting you need a flat head screw and a countersunk hole.
- Are these the same as wood screws?
- No. They have a blunt machine thread and no point, so they are for metal nuts and tapped holes, not for driving into wood.
